Abstract

Die Erfindung betrifft eine Linearlageranordnung mit einer Hülse (1), die eine Innenfläche (8) und eine Mantelfläche (9) aufweist und mit einem Satz von Wälzkörpern (7), die parallel zur Axialrichtung der Hülse (1) auf der Mantelfläche (9) der Hülse (1) abrollen. Die erfindungsgemäße Linearlageranordnung zeichnet sich dadurch aus, dass die Hülse (1) im Querschnitt kreisringförmig ausgebildet ist und einen axial durchgehenden Schlitz (3) aufweist.

The invention relates to a linear bearing arrangement with a sleeve (1) which has an inner surface (8) and a lateral surface (9) and a set of rolling elements (7) which are parallel to the axial direction of the sleeve (1) on the lateral surface (9). unroll the sleeve (1). The linear bearing assembly according to the invention is characterized in that the sleeve (1) is annular in cross-section and has an axially continuous slot (3).
